Very interesting; I'd been thinking of religion in terms of memetic drift, but that mental disorders can, under the right circumstances, contribute greatly to religion is simultaneously fascinating and disturbing. Possibly even explicative.

Actually, some of the core Christian beliefs were decided on by committee. Early Christian churches were highly diverse and sometimes believed in radically different things. Then there were councils that decided that they were heresies and wiped them out

More modern research has shown that Robert Sapolsky was simply mistaken to assume religion is a mental disorder, and its origins have more to do with what neuroscientists today are calling a "complete" mystical experience more so than anything else.
